This question already has an answer here:

I'm looking to replace our SQL Server:

HP Proliant DL360 G4
2x 64-bit Intel Xeon 3.60 GHz, 1M Cache, 800 MHz FSB
4GB RAM DDR2
HP Smart Array 6i
2x 146GB SCSI 15K (RAID 1)

With this:

HP ProLiant SE316M1
2x Intel Xeon L5520 (8M Cache, 2.26 GHz, 5.86 GT/s Intel QPI) Nehalem
16GB RAM DDR3
HP Smart Array P410 512 MB BBWC Cache
2 x 120GB Intel DC S3500 SSD (RAID 1)

I'm also upgrading from SQL Server 2000 and Windows 2003 to SQL Server 2008 R2 and Windows 2008 R2.

I understand the SE316M1 is basically a DL160 G6.

I know our current setup is so ancient (10-year-old) that almost anything can be a big improvement. And this new setup is not a big deal either (5-year-old and pretty unexpensive). But I want to do something as good as I can with my limited budget, but also very reliable.

My biggest concern is the P410 Smart Array and the SSDs (Intel DC S3500). I understand they're compatible, the S3500 is a decent and reliable SSD, and that the P410 won't be a bottleneck for the SSDs.

But what is the Battery Backed Write Cache (BBWC) Module for? Is it a must? What would I be missing in this setup if I don't have it? I'm reading this: HP Smart Array P400/256MB SAS Controller BATTERY. Would I loose performance whith those Intel SSDs? The server will be protected with a UPS. Sorry, I'm a bit confused here! Thanks!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Typically a migration is a fair bit of effort in an enterprise and going from Windows 2003 to Windows 2008 rather than skipping that and going straight to Windows 2012 seems like trading up your horseless carriage to a Model-T Ford when the same amount of effort would get allow you to get, say a Tesla. – HBruijn Jul 28 '15 at 18:42

Yes. You need a BBWC on any Smart Array controller in which you wish to use SSD drives.
